This will be the second time this year an audience of American students will hear from Trudeau directly on why the Canada-U.S. trade relationship is so critical for both countries and why NAFTA needs to be salvaged.

He told students at the University of Chicago in February that tearing up NAFTA — a threat made repeatedly by U.S. President Donald Trump — would hurt millions of Americans.

This is the 16th time Trudeau has taken a working trip to the U.S. since becoming prime minister in 2015 and the 10th since Trump became president.
